Air tools
Grock - August 18th, 2004 at 11:45 PM

I am considering purchasing an air compressor and getting a sander, grinder and other tools to go with it (rather than buying electric ones).

I was just wondering if, for the purpose of body work, a random sander is better than just a plain sander?

Whilst i am at it, is it significantly better to get a 7" grinder over a 4"?

make sure you get a random orbital, they usually have a lock out so it can do straight orbital or both. Make sure you get the biggest compressor you can afford especially for tools like these that are heavy on the air. Say a 16cfm (not direct drive) with a largish tank.

yep I agree with the "size does matter" I have a 13cfm compressor and its usless, its working too hard,go for a 17cfm if you can get one cheap. 4 or 7" grinder? depends on where you're trying to fit it or what your using it for.. air tools are good to use though..

I did the splitty with an air drill with a wire brush in it, rips off everything but the metal, the tools stay cool and I used about 6 cheap wire wheel
easy!

thanks for the advice...

why are direct drive compressors not as good?

they drive the cylinder at a one to one ratio, they are therefore much slower to spool up + they are generally noiser. Trust me I have one and its a dog but it was cheap :)
